Does a javascript function call run before the entire script is finished parsing? -


i know javascript executes code in sequential order. trying identify whether of code run instantly, "line after line", after each function compiled executed, or immediate functions calls in script wait entire script finish parsing before run.

i'd better understanding of way javascript parses , execute code. external scripts, seem bit hard observe in console log.

one applicable use, try , intercept 'interactive' document.readystate possible within external script, due fact "interactive" state can fire extremely @ times. per http://bugs.jquery.com/ticket/12282#comment:15

no. entire content of script tag (regardless of whether inline or external) must parsed before can evaluated.

this because of way javascript 'hoists' variable , function declarations top of scope: http://elegantcode.com/2011/03/24/basic-javascript-part-12-function-hoisting/
